  • Structural Studies of the Fe/ La2O3 nanocomposite obtained by mechanochemical milling 
    Lalaoua, S.; Bouzabata, B. (Université Frères Mentouri - Constantine 1, 2016-12-15)
    Rare-earth oxides as Y2O3 and La2O3 evenly dispersed in Fe matrix constitute ODS alloys with potential applications in nuclear power plants .Dispersion of the above oxides can be obtained from various synthetic routes. ...
  • Study on the solid state reaction between Co/Ni bilayer film and silicon substrate 
    Fiad, H.; Bouabellou, A.; Sedrati, C. (Université Frères Mentouri - Constantine 1, 2016-12-15)
    Billayers of pure Cobalt and nickel films were evaporated alternatively on (100) monocristalline silicone substrate. After annealing, in a vacuum furnace from 300 to 800°C during 20 min, the growth sequence of the phase’s ...
